Dear Sri Vijay Raghavan,

As per the report provided, bore well water has very high hardness and chloride, much beyond the BIS limits specified for potable water.

Further there are few health related chemical parameters, which need to be tested.
For example, fluoride, nitrate etc.

I think you should get the water tested either at or by laboratories approved by Tamilnadu Water Supply and Drainage Board; one can access details from the website on quality assurance (

For specific addresses of the laboratories in Chennai, you can contact, Dhan Foundation, Chennai. Tamil Nadu.
